Technical Field

[0001] The utility model relates to the technical field of motor cooling, in particular to a novel motor cooling device. Background Art

[0002] Motor cooling device is a kind of device that generates a lot of heat during the operation of the motor due to long-term continuous operation. As the heat accumulates, the temperature of the motor itself gradually rises, affecting the power and operation safety of the motor. Therefore, it is necessary to continuously cool the motor during operation.

[0003] However, in actual production, the existing motor cooling device still has some shortcomings:

[0004] The motor cooling device currently mainly uses a fan installed directly on the motor to draw air into the device for cooling. At present, the induced draft equipment is directly installed on the motor, and the fan directly introduces air from inside the workshop. The air temperature inside the workshop is high and there are many impurities, which has many unfavorable factors for the maintenance of the motor.

[0005] In view of the above problems, the utility model document proposes a novel motor cooling device. Utility Model Content

[0007] The utility model provides the following technical solutions:

[0008] A new type of motor cooling device, which cools down the motor working in the workshop, includes:

[0009] A motor housing, wherein an output shaft is disposed in the motor housing, a fan blade is installed outside the output shaft, and a plurality of heat dissipation holes are disposed in the motor housing;

[0010] The induced draft device is connected to the motor housing and is used to input air outside the workshop into the motor housing to cool it.

[0013] In a possible design, a first dust-proof net is provided in the air duct.

[0014] In one possible design, the dustproof box is laterally provided with a through hole parallel to the air duct, and the dustproof box is detachably provided with two movable dustproof nets, and the apertures of the two movable dustproof nets are different. The aperture of the movable dustproof net that the external air first contacts when entering the air duct is larger than the aperture of the movable dustproof net that contacts later.

[0020] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0021] Beneficial effects:

[0022] In the utility model, heat is generated during the operation of the motor in the workshop, causing the internal temperature to rise. The application document uses an axial flow fan to introduce clean and low-temperature air outside the workshop into the air duct, and the first dust-proof net in the air duct can perform a coarse filtration on the introduced air, and then pass it through the dust-proof box for secondary filtration, and finally enter the motor housing through the air outlet duct to cool the motor body. Since the motor housing is provided with a first heat dissipation hole and a second heat dissipation hole, and the rotation of the motor drives the fan blades on the output shaft to rotate, the air flow rate in the motor housing can be increased, and the low-temperature air introduced from the outside can be discharged through the heat dissipation holes after quickly exchanging temperature with the motor, thereby effectively improving the heat dissipation efficiency of the motor, and the dust-proof nets provided at the heat dissipation holes can prevent external dust from clogging the heat dissipation holes.

[0023] In the utility model, the first wind speed transmission and the second wind speed transmission arranged in the induced draft duct can monitor the air flow in the induced draft duct. When the flow rate monitored by the first wind speed transmission is greater than the air flow rate monitored by the second wind speed transmission, it means that the movable dustproof net in the dustproof box is clogged. At this time, the movable dustproof net can be replaced by fixing bolts.

[0024] In the utility model, since a plurality of branch pipes are provided, the introduced low-temperature air can enter the motor from a plurality of positions and generate heat exchange with the inside of the motor, which can greatly improve the heat dissipation efficiency of the electronics.

[0025] From the above, it can be seen that the utility model introduces clean and low-temperature air from outside the workshop into the motor through a pipeline, thereby better reducing motor problems during motor operation, improving motor operation efficiency, and filtering floating objects and other impurities in the air through a filtering device to prevent impurities in the air from affecting the normal operation of the motor.

[0026] The utility model also has the characteristics of simple structure, convenient installation and strong practicability, and can be widely used in cooling motors. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] On the basis of the fourth embodiment, the dustproof box 14 is transversely provided with a through hole 18 parallel to the air duct 7, and two movable dustproof nets 16 are detachably installed in the dustproof box 14. The apertures of the two movable dustproof nets 16 are different, and the aperture of the movable dustproof net 16 that the external air first contacts when entering the air duct 7 is larger than the aperture of the movable dustproof net 16 that contacts later, so that the cleanliness of the air entering the air duct 7 can be further improved.

[0060] Embodiment 10

[0061] On the basis of the seventh embodiment, the first dustproof net 11 and the movable dustproof net 16 are both made of non-woven fabric, which has good filtering effect and durability.

[0062] From the description of the above embodiments, it can be seen that the new motor cooling device provided by the present invention has the advantages of simple structure, good heat dissipation effect, good filtering effect, etc., and can effectively reduce the working temperature of the motor in the workshop and improve its working efficiency and stability.

[0063] However, as is well known to those skilled in the art, the working principles and wiring methods of the axial flow fan, the first wind speed transmission, and the second wind speed transmission are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0064] The working principle and use process of this technical solution are as follows: when the motor starts working, the fan blades 2 will rotate with the output shaft, generating an internal airflow circulation to initially dissipate heat for the motor. At the same time, the electric draft device is started, and the axial flow fan 12 draws the air outside the workshop into the draft duct 7 through the draft port 10. After preliminary filtration by the first dustproof net 11, it is filtered through two movable dustproof nets 16 in the dustproof box 14 at multiple stages, and finally enters the motor housing 1 through the branch pipe 8 and the air outlet pipe 9. Under the action of the draft device, the hot air in the motor housing 1 is discharged, and the clean cold air from the outside is introduced, thereby improving the heat dissipation effect of the motor. At the same time, the dust-proof nets in the first heat dissipation hole 3 and the second heat dissipation hole 5 can prevent dust from entering the motor, ensuring the normal operation of the motor.

[0065] When the air volume needs to be adjusted, it can be achieved by controlling the size of the electric valve. When the motor stops working, the electric induced draft equipment will also stop running to avoid unnecessary energy consumption.
